Trinseo (NYSE: TSE), a global materials company and manufacturer of plastics, latex binders and synthetic rubber, and the Chemical Marketing and Economics (CME) group of the American Chemical Society’s (ACS) New York Section announced that Christopher D. Pappas, Trinseo’s President and CEO, was honored with the Leadership Award for Outstanding Corporate Reinvention, in part due to the Company tripling in value during the preceding three years.

Pappas accepted the award on behalf of the entire Company during a ceremony at the Metropolitan Club of New York on December 5. In his remarks, Pappas credited his success at Trinseo to his employees, his family, his mentors, and the foundational values they inspired in him.

“Trinseo is the top-performing stock in the chemical sector since we went public in June of 2014,” Pappas said. “Believe me, that doesn’t happen without a tremendous amount of effort from all 2,200 of Trinseo’s employees. I accept this award on behalf of all of them.”

Few companies in the chemical sector have tripled in value in the last three years. This achievement has been the result of Pappas' visionary leadership and focus on safety, technology, financial discipline, and growth.

In 2014, Trinseo was renamed from Styron, completed a successful IPO on the New York Stock Exchange, and saw a 270% increase in its stock price to date. The company also has an exceptional track record on employee safety, with an OSHA recordable rate of 0.07 – which places the company among the top five percent of chemical companies.

"The success of Trinseo, a company that combines the dynamism of a start-up with the complexity and depth of a multinational conglomerate, could not exist without the exceptional vision and leadership of Chris Pappas," Mr. George Rodriguez, Leadership Awards founder and CME Past Chair noted while recounting the firm's heritage at Dow Chemical and impressive growth story since becoming fully public and independent.

Pappas joined the company at its formation in 2010 when it was carved out from its former parent The Dow Chemical Company through a leveraged buyout with private equity firm Bain Capital Partners. Under his leadership, the company established independent operation, defined a new vision and culture, dramatically improved its financial position, launched expansions and capital investments.

"We truly believe we have set up Trinseo as a company with a culture and a set of principles that will allow us to tackle our next set of challenges as we look to 2018 and beyond," Pappas said.

Pappas has a 35-plus year distinguished career and proven operating experience in the chemicals and plastics industry, and is an accomplished leader of complex global businesses. Pappas started his career at The Dow Chemical Company in 1978. In 1996 he joined DuPont Dow Elastomers LLC where he was Vice President of Ethylene Elastomers and later Commercial Vice President. He joined NOVA Chemicals Corporation in 2000 and held positions as Senior Vice President & President, Styrenics; Chief Operating Officer; President and Chief Operating Officer; and finally in 2009 as President and CEO.
